Patent JP-S58197525-A (JP)
Title: Temperature controller
Inventor: UMEDA ARATA
IPC: G05D23/20
Filed: 1982-05-14
Abstract: PURPOSE:To perform heating in a short time and to prevent overshooting by powering on a heater fully for quick heating up to critical temperature set between set temperature and control point temperature, and then decreasing the duty cycle speedily. CONSTITUTION:The outut of a temperature detecting element 1 is inputted to a V/F converter 2 which varies in duty cycle with temperature to be converted into a pulse interval, and also inputted to a comparator 3. The outputs of the circuits 2 and 3 are supplied to an OR circuit 4, whose output is supplied to a solid-state relay SSR5 to intermit a current to the heater 6. Quick heating is carried out with a 100% duty cycle initially, but the output of the comparator 3 goes down to L when the temperature attains to the critical temperature between the set temperature and control temperature to decrease the duty cycle speedily under the control of the V/F converter 2, so that the temperature rises gradually. Consequently, the temperature rises in a short time without overshooting. This is suitable for the fixing device of a copying machine.

Filed: 1984-04-23
Abstract: PURPOSE:To form simply a high-frequency coil for a nuclear magnetic resonance device by a method wherein capacity coupling is performed electrically, using plural strip metallic plates, by lying electric insulators between each metallic plate. CONSTITUTION:High frequency electric current supplied to electrodes 2 of a high frequency coil flows through plural metallic plates 4 and an electric insulator 5 laid between metallic plates and generates high frequency magnetic field 3.

Title: Liquid crystal display device
Inventor: MURAMATSU HIROMOCHI
IPC: G02F1/1347
Filed: 1981-05-28
Abstract: PURPOSE:To prevent a liquid crystal from being mixed into other layers for charging of the liquid crystal and make it possible to charge a small quantity of the liquid crystal, by providing inlets, through which the liquid crystal is charged to respective liquid crystal holding layers, in different positions on the outline of a liquid crystal holding substrate. CONSTITUTION:Liquid crystal holding layers 5a-5d are formed with liquid crystal holding substrates 2, seals 4, etc., and intervals of substrates 2 are held by spacers 6a-6d. Liquid crystal charging inlets 3a-3d are arranged in different positions on the outline of substrates 2. Therefore, when one charging inlet 3a is immersed in the liquid crystal, other charging inlets 3b-3d are not brought into contact with the liquid crystal to prevent the mixing of the liquid crystal. Further, since charging inlets are provided at apexes of a polygon, the area of the contact between the liquid crystal and the charging inlet is small, and thus, even a small quantity of the liquid crystal is charged.

Title: Information processor
Inventor: HONMA HISASHI
IPC: G11C8/00
Filed: 1982-05-13
Abstract: PURPOSE:To obtain an information processor which is free from the limitation with the size of a user program even though the size of a control program is increased, by providing a means to produce a part of the selection information of a memory chip independently of an address. CONSTITUTION:A data is written to a bank selecting register 3 via a bus 7 and on the basis of an instruction given from a CPU. Thus the chip of an ROM6 is selected. If it is defined that an address decoding circuit 2 generates a chip selection signal only, only the data written to the register 3 is decoded. As a result, a program is fetched from a designated chip of the memory 6. Therefore it is possible virtually to store a program of a size several times as large as a memory chip into an address space equivalent to the capacity of the chip of the memory 6.

Filed: 1982-05-13
Abstract: PURPOSE:To stop temporarily a motor for driving a tape at a program searching position, by providing a switching circuit which drives the motor controlled by the output of a bistable multivibrator operating by the output of an intermusic gap detecting circuit. CONSTITUTION:For example, a tape recorder is in cue or review mode. In this case, switches S1-S3 are all on. Therefore, the output of a reproducing head is amplified by a sound recording and regenerative amplifying circuit 1, whose output is supplied to an output circuit 2 and the intermusic gap detecting circuit 3. The detecting circuit 3 generates a low-level output when a reproduced signal is applied. When an intermusic nonrecording part is detected, a high-level pulse signal with specific length appears at its output terminal. Therfore, while the reproducing head generates the reproduction output, one transistor (TR) Q1 constituting a bistable multivibrator together with the other TR Q2 turns on, and the other TR Q2 turns off.

Title: Controller for induction motor
Inventor: WADA EIKICHI
IPC: H02P5/74
Filed: 1978-07-05
Abstract: PURPOSE: To prevent hunting, perform stable acceleration and simplify a control circuit, by equalizing the secondary resistances of two induction motors to each other when a single body is driven by the plural motors.  
     CONSTITUTION: The induction motors IM1, IM2 are connected to a power source through circuit breakers CB1, CB2. The secondary sides of the motors are connected to electrodes ED1, ED2 immersed in a common electrolyte EL in a container TA. A liquid resistor is composed of the container TA, the electrolyte EL and the electrodes ED1, Ed2. Since the electrodes for the secondary resistances of the motors are immersed in the electrolyte in the same container, the effect of the temperature and concentration of the electrolyte upon the motors is the same. Therefore, the secondary resistances of the motors are always equal to each other. As a result, the load is equally shared by the motors and their run is stabilized.

CONSTITUTION:A pulse voltage Va of an image sensor 44, which is obtained by scanning an image projecting light by the image sensor 44 is compared with a reference voltage Vc which is varied stepwise at every one scan of the image sensor 44, the number of picture elements by which the pulse voltage Va becomes larger than each reference voltage Vc is counted at every reference voltage Vc, and based on a feature of a distribution characteristic curve against the reference voltage Vc of its counting value, whether an image exists or not is discriminated. In this regard, as for the feature of the distribution characteristic curve, for instance, an area of the area exceeding the reference voltage Vc by which the number of picture elements has changed suddenly is derived, and due to a fact that this area is contained in the set range, whether the image exists or not can be discriminated. In this way, whether the area is the area containing an image having a contrast by which an AF mechanism is operated correctly enough or not can be discriminated.
